Aortic dissection is an acute injury of the aortic intima due to various factors from the outside or itself. The rapid blood flow enters the middle layer of the aortic elastic force from the breach and expands longitudinally along the aorta to form a true and a false two lumens. Aortic dissection is a rare, high-risk cardiovascular disease with a low incidence, but it is extremely harmful. Lesions can affect the systemic system, without treatment, the natural prognosis is poor. Surgery is the most effective treatment, especially for Stanford A and high-risk Stanford B dissection. With the increase of the incidence of aortic dissection, the diagnosis and treatment and nursing technology have developed rapidly in recent years, but the mortality rate is still high due to the complex, rapid changes and complications. This article reviews the current status of preoperative aortic dissection in order to improve the understanding of clinical nurses and provide a reference for the perioperative nursing intervention study of aortic dissection.
